Benefits of technology

The present invention is a navigation system that provides guidance for traveling a route that includes at least one road segment. The system uses data from a geographic database to identify features that are visible from the road segment and determines their importance rating based on their permanence (how long they have been visible), seasonal dependency (how impacted they are by season), visibility (how well they can be seen), and prominence (how big and far they are from the road segment). The system then references the feature with the highest importance rating in the guidance message. The importance rating takes into account attributes such as permanence, seasonal dependency, visibility, prominence, feature extent (how long the feature is), and preferred name (if there is a name for the feature in the database. This invention helps drivers to better understand and navigate their routes.

Problems solved by technology

Some end users may get confused as to their orientation and where to turn.

Embodiment Construction

I. Navigation System

[0021]FIG. 1 is a block diagram of a navigation system 100 associated with a computing platform 102, such as an in-vehicle navigation device, a personal navigation device, a mobile computer, mobile telephone, personal digital assistant (PDA), personal computer, or any other computer, according to an exemplary embodiment. The navigation system 100 is a combination of hardware and software components. In one embodiment, the navigation system 100 includes a processor 104, a drive 106 connected to the processor 104, and a non-volatile memory storage device 108 for storing navigation application software programs 110 and possibly other information.

[0022]The navigation system 100 also includes a positioning system 112. The positioning system 112 may utilize GPS-type technology, a dead reckoning-type system, or combinations of these or other systems, all of which are known in the art. The positioning system 112 may include suitable sensing devices that measure the trave...

Abstract

A method of operating a navigation system to provide a route guidance message for traveling a route is disclosed. A plurality of features visible from a road segment of the route is obtained from a geographic database associated with the navigation system. An importance rating for each of the identified features is determined. The guidance message references the identified feature having a highest determined importance rating. The importance rating considers a permanence or a seasonal dependency of the identified feature.

Description

REFERENCE TO RELATED APPLICATIONS[0001]The present application is related to the co-pending application entitled “METHOD OF OPERATING A NAVIGATION SYSTEM TO PROVIDE ROUTE GUIDANCE” filed on the same date herewith, Attorney Docket No. N0321US, the entire disclosure of which is incorporated by reference herein.
